Hey guys, I'm sure the thread title sparked an interest in some of you and may seem bizarre to others. I began to smoke marijuana at the age of 17 (I'm 19 now), and I must say that I do enjoy smoking and the camaraderie that accompanies it. Now I've never done any other drugs but the use of...

Homework Statement ∫(e^x)/(√4-e^(2x)) Homework Equations arcsin of x The Attempt at a Solution I know how the problem should be solved and have an idea of what the final answer will be. My only question is, how would I take out the four from the square root, in order to make it...

Hey everyone, So I got a D+ on my first Physics exam. I always have a goal of achieving straight A's in a semester and now I feel that that's gone down the drain. Maybe one of you guys can help me out here. The worst test (out of 3) is only worth 10% of my final grade (assuming that this test...

Hey guys, So today I was in my Physics lab and a small argument arose. We had a pre-test with a question that stated: "Jan pushes on a refrigerator just enough to barely get it to move at a constant speed. Is her force on the refrigerator greater than, less than, or equal to the force of...

I've always had some trouble with these terms and using them interchangeably but I feel like I've finally made the clarification for myself. In the most rudimentary terms, it seems that the mass of something is the amount of "stuff" occupying it, whereas weight is the force of gravity on...

I remember sitting in my Pre-Calculus class my senior year of high school and thinking to myself "what a wonderful course". Ever since then, my general appreciation for learning has increased significantly and I now tend to view learning opportunities as a chance to grow, no matter the subject...

Hey everyone! Just wanted to start a small discussion. Is anyone here interested in becoming a Walt Disney World Imagineer? If so, how much progress have you made, and why do you feel like this career choice is apt to your personality?

Hello everyone, I just want to write a small story that hopefully some of you guys can help me out with: Ever since I was young, I always looked up to my uncle who was a Civil Engineer. He was the main reason that I ever decided to study engineering in the first place because of all the cool...

Okay I finally got the answer but only by comparing them to other online resources. I'm still not entirely sure on how to do the actual problem. I wouldn't mind discussing this further but if you guys need to go do other things, that's okay. Thanks for the help anyway.

Does it mean that the function is differentiable within those bounds?

I understand the bit about the Fundamental Theorem of Calculus coming into play but I thought that you just substitute the bounds where the variables are. For example, the book gives us the example of: Integral with lower bound of 1 and upper bound of x, (t^3)dt. The answer is given as merely x^3

I'm comparing my answers with a similar problem in the book and there aren't any equations, only numerical answers.

I am completely lost :(

So would the answer be: x^2 + 144?

Do I take the anti-derivative and plug in 5?
